Quizplus · Accepted Answer

A main effect is a consistent difference between levels of a factor. It refers to the effect of a single independent variable on the dependent variable, regardless of the levels of any other independent variables. Null case refers to the absence of an effect, interaction effect refers to how the effect of multiple independent variables is not simply additive, and crossover case refers to when the effects of two independent variables switch or cross over each other.
